Most U.S. universities have made explicit commitments to educating economically diverse student bodies; however, the higher education system is highly stratified. In this paper, we seek to understand stratification in the wake of the Great Recession by examining enrollment among students from differing income backgrounds by institutional type. Two theoretical frameworks suggest different conclusions. A Disaster Capitalism framework suggests that in places where the recession was most severe, enrollment by income would become stratified than in places where the downturn was less severe. In contrast, Effectively Maintained Inequality would suggest that enrollments were already effectively stratified by income and would not necessarily be sensitive to exposure to an economic shock. Employing fixed effects modeling and novel data based on the tax records of 30 million Americans, we examine income composition by institutional type from 2004 to 2012. We find that although stratification by institutional type worsened during the recession and subsequent recovery, patterns of economic stratification were more intense for institutions that enrolled students from states hardest hit by the recession. We conclude that these patterns are consistent with an Effectively Maintained Inequality framework. During the recession, the top quintiles continued to enjoy their longstanding disproportionate enrollment in the most selective institutions. For the bottom quintiles, the longstanding marginalization from 4-year college going persisted through the recession. These stratification patterns, however, were not more pronounced in places hardest hit by the recession.

Porcine circovirus type 2 (PCV2) is the major causative agent of postweaning multisystemic wasting syndrome which leads to significant economic losses in the global swine industry. In China, there is a widespread dissemination of PCV2 infection in the pig population. Serological diagnosis of the disease is considered as an effective control measure.

Objective: Ca overload of muscle fibers is one of the factors that secondarily aggravate the development of Duchenne muscular dystrophy (DMD). The purpose of this study is to evaluate the effects of the Ca channel modulator 2-aminoethoxydiphenyl borate (APB) on skeletal muscle pathology in dystrophin-deficient mice.
Methods: Mice were randomly divided into six groups: wild type (WT), WT+3 mg/kg APB, WT+10 mg/kg APB, , +3 mg/kg APB, +10 mg/kg APB.

Background: Epidermal growth factor receptor 4 (ERBB4) and neuregulin 4 (NRG4) have been shown to reduce steatosis and prevent the development of non-alcoholic steatohepatitis in mouse models, but little to nothing is known about their role in non-alcoholic fatty liver disease (NAFLD) in humans. This study is the first to investigate the expression of and mRNAs and their role in lipid metabolism in the livers of individuals with obesity, type 2 diabetes and biopsy-proven NAFLD.
Methods: Liver biospecimens were obtained intraoperatively from 80 individuals.

Four new macrolides, spirosnuolides A-D (-, respectively), were discovered from the termite nest-derived sp. INHA29. Spirosnuolides A-D are 18-membered macrolides sharing an embedded [6,6]-spiroketal functionality inside the macrocycle and are conjugated with structurally uncommon side chains featuring cyclopentenone, 1,4-benzoquinone, hydroxyfuroic acid, or butenolide moieties.

We present a new type of elementoboration reaction, the thioboration of terminal alkynes. This method enables highly controllable regio-/stereo-/chemoselective - and -thioboration on demand, affording synthetically versatile and densely functionalized vinyl boron/vinyl sulfide derivatives in a straightforward manner without the need for a transition-metal catalyst.
